Hey guys, I am currently having some problems with my toshiba satelite laptop I first got the blank/black screen when I restarted my computer because I had deleted some registries to make my usb ports work. I have tried everything such as taking all the power supplies out of the computer then draining it, I've took the ram out and put them in different slots. I am currently running on windows 10 was 8.1 but decided to upgrade. Thanks for helping.

I was told to delete some registries inside of Localmachine where the usbs were loaded I can't really remember what it was called though. When I restarted my laptop it did a windows update and crashed I also deleted the USB Hub registries for them to reinstall. Think that's what there called.

Hi

I believe you were ill advised to delete registry entries without first backing up the registry.

I suggest you try restoring to factory settings. Unfortunately all of your data will be lost but it"s better than a dead Toshiba.

Hello, I have found the post that told me what to do.
Expand "HKEY_LOCAL_MACHINE", then "SYSTEM", then "CurrentControlSet", then "Control" and finally expand "class". there should be a folder approximately ten down starting with "4D36E965" select this. Inside if you see any files with UpperFilter or LowerFilters delete them. I deleted the upper and lower filter then it stopped working. Also how would I restart the computer with black screen?

If you don't get a signal in safe mode, and only if, try restoring following these instructions
